JULIUS HAMZA, OF NORWALK, CONNECTICUT.

RAIL-JOINT.

T 0 all whom it may concern:

Be it known that I, JULIUs IIAMZA, a subject of Francis Joseph, Emperorof Austria-Hungary, residing in the town of Norwalk, in the county ofFairfield and State of Connecticut, have invented certain new and usefulImprovements in Rail-Joints, of which the following is a specification,reference being had therein to the accompanying drawings.

My invention relates to new and useful improvements in rail joints, andhas for its object, among other things to construct a rail so that thesame may interlock with the rail adjacent thereto and secured by asingle pin as distinguished from the usual method of securing rail endstogether by plates and bolts.

To these, and other ends, my invention consists in the rail joint,having certain details of construction and combinations of parts, aswill be hereinafter described and more particularly pointed out in theclaims.

Referring to the drawings, in which like numerals of reference designatelike parts in the several figures; Figure 1 is a side elevation of tworails constructed in accordance with my invention and secured together;Fig. 2 is a similar view to that shown in Fig. 1 with the key removed;Fig. 3 is a side elevation, partly in section, of the rail shown at theleft of Figs. 1 and 2; Fig. 4; is a side elevation of the rail shown atthe right'of Figs. 1 and 2; Fig. 5 is an end view of the rail, shown inFig. 8 Fig. 6 is an end view of the rail, shown in Fig. 4; Fig. 7 is asectional view of the rail taken upon line AB of Fig. 3; and Fig. 8 is asimilar view taken upon line CD of Fig. 3; and Fig. 9 is a perspectiveview of the locking key.

I11 the practice of my invention, one end of the rail 1 is constructedsubstantially as shown in Figs. 8 and 5, and the other end substantiallyas shown in Figs. 4: and 6, each end being provided with a tongue 3,which projects downwardly from the top 4 of the rail, as shown in Figs.3 and 5, and upwardly from the bottom 5, as shown in Figs. 4 and 6, andconnected with the top 4 and bottom 5 by means of the angular faces 6.Adjacent to said tongues are the pockets 7 that are of substantially thesame width and parallel with said tongues, and terminate at their openend in the throat 8, having angular sides, corresponding in their anglewith that of the faces 6. Each of the Specification of Letters Patent.

Serial No. 599,427.

rails is provided with a key opening 9, the top and bottom of which aresubstantially parallel with each other, and the top and bottom of therail, and the sides are angular so that the width of the key opening atthe ends is greater than at any point therebetween. The ends of theabutting rails 1 and 2 are secured together by placing the same on theties and moving them toward each other, at which time the tongue 3 uponone of the rails enters the pocket 7 in the other rail, forming aconnection as shown in Fig. 2. They are then secured together by a key10, the body of which has grooved sides 11, and in cross section is thesame as the key opening 9. The key is passed through the key opening 9with the head 12 thereon abutting against one side of the web of therail, and prevented from being accidentally dislodged therefrom by acotter pin 13, projecting through the hole 14 in said key.

In my invention, as herein shown, the rails are secured together by theinsertion of a single key, an operation that requires practically littleor no time, and the engagement of the tongue 3 upon one rail with thepocket 7 in the other rail, cooperates to form a joint that is rigid andwill prevent lateral or endwise movement of one rail in relation to theother.

In minor details my invention may be modified considerably from theconstruction shown in the drawings, and I would there fore have itunderstood, that I do not limit myself to the exact construction hereinshown and described, but claim all that falls fairly within the spiritand scope of my invention.

Having described my invention, what I claim as new and desire to secureby Letters Patent, is

1. A rail constructed with a tongue ateither end thereof, the tongue atone end projecting downwardly from the top of said rail, and at theother end upwardly from the bottom thereof; a pocket at each end of saidrail adjacent to said tongue, the pocket at that end of the railadjacent to the tongue projecting downwardly from the top thereof,opening at the bottom of said rail, the pocket at that end of the railadjacent to the tongue projecting upwardly from the bot tom thereof,opening at the top of said rail.

2. A rail constructed with a tongue at either end thereof, the tongue atone end projecting downwardly from the top of sald rail, and at theother end upwardly from the bottom thereof; a pocket at each end of saidrail adjacent to said tongue, the pocket at that end of the railadjacent to the tongue projecting downwardly from the top thereof,opening at the bottom of said rail, the pocket at that end of the railadjacent to the tongue projecting upwardly from the bottom thereof,opening at the top of said rail; and a key opening through the Web ofsaid rail at substantially a right angle to said pocket.

3. A rail constructed with a tongue and a pocket at each end thereof,said pocket opening into a throat With flaring sides, and 15 said tongueterminating at its bottom end in a portion having flaring sides Withsubstantially the same angle as those of said throat; and a key openingthrough the Web of said rail at substantially a right angle to said 2()pocket.

In testimony whereof I aflix my signature in presence of two Witnesses.
